TabulaX: Leveraging Large Language Models for Multi-Class Table Transformations

Summary: TabulaX classifies columns into string, numerical, algorithmic, or general transformations, then uses LLMs to synthesize tailored, human-interpretable formulas/code. It broadens transformation coverage and improves accuracy over prior automation methods on real-world data. (summarized by gpt-5.6-luna on Jul 24 2026)
